Precipitation, air and soil temperatures, soil moisture, and other environmental variables were measured daily for several weeks following the seeding of alfalfa ( Medicago sativa L.), red clover ( Trifolium pratense L.), and birdsfoot trefoil ( Lotus corniculatus L.) on 52 occasions. Regression analysis was used to determine the significance of these variables to stand establishment. Environmental variables explained much of the variation in initial legume populations, but variability in stand counts several months after seeding was explained primarily by the classification variable “seeding date,” rather than by the specific environmental variables associated with seeding dates.
